For the bucket tip position control of the excavator, a traditional hydraulic excavator system was exchanged into an electro-hydraulic one. EPPR valves are attached to the traditional MCV and hydraulic joysticks are replaced by electronic ones to develop the electro-hydraulic system. To control the electronic pump with a good performance, the control logic for the pump is deduced from the AMESim simulation and the experimental method on the test bench. To get a good position control performance of the excavator bucket tip, PI+AntiWindup controller is selected as a position controller. The experimental results showed the good controllability for the electro-hydraulic excavator system on the test bench.

The railway signaling system consists of micro-computerized vital devices on board and ground, which are connected to one another by track circuits, and interlocking equipment for route control. Therefore it is important to validate the required functions of developed system and interface between developed signaling systems. To verify the conditions and functions of signaling functions, the laboratory prototype test bench, which consists of personal computers LAN, will be developed. In this paper design of signaling system test-bench for high-speed signaling is described and developed software module are presented.

Among various rapid prototyping processes, stereo-lithography process which can manufacture transparent prototype is known to be the greatest in the form & dimensional accuracy and surface roughness. In this paper, bench mark tests of 4 stereo-lithography-type rapid prototyping apparatus were carried out using transparent materials. The test includes measurement of mechanical properties, form accuracy, building speed and manufacturing cost. It was observed that ViperPRO of 3D systems is advantageous in the mechanical properties and building speed, RM600011 of CMET in sub-milli scale form accuracy and manufacturing cost, and relatively economical Eden500V of Objet is great in tensile strength at room temperature.

Fast neutrons with a broad energy spectrum, with which it is possible to evaluate nuclear data for various research fields such as medical applications and the development of fusion reactors, can be generated by irradiating proton beams on target materials such as beryllium. To generate short-pulse proton beam, we adopted a deflector and slit system. In a simple deflector with slit system, most of the proton beam is blocked by the slit, especially when the beam pulse width is short. Therefore, the available beam current is very low, which results in low neutron flux. In this study, we proposed beam modulation using a buncher cavity to increase the available beam current. The ideal field pattern for the buncher cavity is sawtooth. To make the field pattern similar to a sawtooth waveform, a multiharmonic buncher was adopted. The design process for the multiharmonic buncher includes a beam dynamics calculation and three-dimensional electromagnetic simulation. In addition to the system design for pulsed proton generation, a test bench with a microwave ion source is under preparation to test the performance of the system. The design study results concerning the pulsed proton beam generation and the test bench preparation with some preliminary test results are presented in this paper.

It is said that the verification effort occupies about 50-70 percent of the total effort of a System-On-A-Chip. This paper aims to develop a test bench automation tool based on the abstraction of the interface protocols. This tool will allow designers to describe their test benches in a high level language such as C rather than VHDL or Verilog. It helps designers to save their verification time and effort.

Although current RFID technologies can provide wide advantages in food industry area, most food companies do not consider willingly adopting this technology yet. This paper will present how the effective implementation of RFID systems in food industry could be realized. To Measure the importance of RFID systems, this study utilized the BMT(Bench Mark Test) methodology using RFID systems that were composed of tag and reader. After conducting this study, it suggests the effective tag attachment methods on the objects. The results are shown that the excellent tag product is a RFCamp and a fixed reader of Thingmagic Mercury 4 is the best product. Also, a portable reader of Motorola MC9090-RFID is recommend to the highest product. Therefore, this test is useful for selecting the best RFID systems to the food industry area. In addition, this study displays the effective tag attachment method to each bottle that was used to the experiments in food industry. Therefore, this study is contributed to the not only importance in the government IT areas as a growth engine but also the importance for consumer as a right for the knowledge about the food quality.

방사성 폐기물 소각기술 개발 자립의 일환으로 한국에너지연구소에서는 실험용 방사성폐기물 소각공정을 설치하여 운전중에 있다. 이 공정은 소각경험의 습득 및 소각 특성 시험, 여과기의 성능시험 등을 위하여 설치되었다. 종이와 폴리에틸렌 모의폐기물을 소각하여 공정의 경제성과 운전성을 나타내는 감용비과 제염계수를 결정하였다. 제염계수로부터 소각설비의 허용 비방사능치를 얻어내고 설비의 감용비를 산출하는 방법을 기술하였다. 실험용 소각공정에서의 가연성 폐기물에 함유된 핵종에 대한 인수기준치를 상기방법을 이용하여 제시하여 보았다.

본 논문은 고차가지구조 폴리머인 AEO3000 를 이용한 UV 광경화 성형 공정을 제안하고자 한다. 이는 기존의 바이오칩 제작에 사용되는 PDMS 보다 경도가 높아 금속 전극 형성이 용이하고 제작 공정이 빠르다는 장점을 갖는다. AEO3000 을 이용하여 본 연구에서는 4 개의 소자를 전기적 유체적으로 연결할 수 있는 전기유체 통합벤치를 제작하고 미소유체 혼합소자와 세포분리소자를 연결, 본 소재와 공정이 바이오칩에 적용될 수 있음을 검증하였다. 전기 유체적 특성 분석 결과 전기적 접촉 저항은 $0.75{\pm}0.44{\Omega}$으로 충분히 작은 값을 보였으며, 유체 접속의 압력 저하는 8.3kPa로 기존의 튜브 연결 방법 대비 39.3% 개선된 값을 보였다. 통합벤치에 접속된 소자에 활성 및 비활성 효모를 주입하여 순차적인 혼합 및 재분리를 성공적으로 구현함으로써 본 소자에 적용된 AEO3000 및 UV 광경화 공정이 생체시료의 처리에 적용될 수 있음을 실험적으로 검증하였다. 이는 바이오 의료 분야에 적용 가능한 생체 친화적 소재의 고속 생산에 응용될 수 있다.
